Using the at-rest earth pressure function, the area loads are calculated by increasing by the factor k0/kah in compliance with DIN 4085 Section 6.4.3.
Alternatively, it is possible to determine the demands placed on the wall by area loads according to the theory of elastic half-space. The required concentration factor is specified in the following dialog box, if the upper check box is activated.
According to the EAB, R 23 (Paragraph 2), for systems with at least two rows of anchors or struts, at-rest earth pressure can be kept constant from the lowest support. To do this, activate the check box at the bottom of the dialog box.
